Pacing Tips
- •Aim for even or slightly negative splits — running the second half at the same pace or slightly faster than the first.
- •Halfway check: At halfway, you should have used slightly less than 50% of your planned total time.
- •Your pace per mile/km should vary by no more than 5–10 seconds in the first 80% of the race.
